<div dir="ltr"><div dir="ltr"><div><span>Dear All,<br></span></div><div><span>My first concern is, how are atomic positions of crystal structures generated? I also want to model Na-Ag2O using Quantum Espresso, therefore I seek assistance in determining the atomic
position of the metallic element, sodium(Na), at the Tetrahedral Interstitial Site
(TIS) within the bcc structure of Ag2O. Could someone provide guidance
on how to accurately position the element at the TIS?</span><span></span> <br></div><div><span>Thank you for your help.</span><span></span>
